[0028] Adjustment principle: people place the upper die on the lower die to form a die set by using a forklift, then move it to the front extension frame 9, and then use the front extension frame 9 to move to the bottom assembly seat 5, and then use the side extension machines 3 to squeeze the die set from both sides to correct its position on the bottom assembly seat 5, and then use the bottom elevator 4 to lift, and then use the top elevator 2 to control the top assembly seat 6 to descend, and then fix the upper die on the top assembly seat 6, and then place the raw materials in the forming groove of the lower die, and then use the top elevator 2 to control the top assembly seat 6 to lower the upper die, thereby extruding and forming.

[0029] In order to cooperate with the lifting adjustment, the top telescopic section of the bottom elevator 4 is axially connected with the lower end of the bottom assembly seat 5.

[0030] In order to reduce the bottom moving friction, bottom support rollers 10 are installed on the upper ends of the bottom assembly seat 5 and the front extension frame 9.

[0031] The lower die is placed on the bottom support roller 10 through the lower die swing, and the movement of the lower die is reduced through the bottom support roller 10.

[0035] The position of the lower die can be monitored in real time through the pressure monitoring module 13, and the angle of the two sides of the lower die can be known by the size of the value of the different position pressure monitoring module 13, when the values of the two sides of the pressure monitoring module 13 are the same, it means that the lower die is adjusted to the correct position and angle.
